As an agency often involved with spatial information, the CGS is moving more and more to dynamic GIS data presentation for ease-of-use and for the many options that GIS tools allow. Almost all of our current projects and publications have substantial GIS components.
Many of our publications include GIS_Data directories as part of the downloadable package. As always, this data is free and may be used within many standard GIS applications. We do most of our GIS production work using ArcGIS from ESRI, with the Avenza app as the go-to for field mapping and data geolocation.
We will be building out our library of web applications that offer refined ‘views’ of Colorado geology and the associated derivatives of use to our various constituencies. At the moment, we are assessing our entire GIS dataspace for new packages that we can bring online in the next months.

GENERAL GEOLOGY
ON-001 — Colorado Earthquake and Fault Map — shows a variety of information including Cenozoic faults. (supersedes publications B-46; B-52; B-52B, and IS-60)
ON-04-01 — StateMap Progression Map — shows the quadrangles that have been geologically mapped across the state, both USGS and CGS maps. Of Colorado’s approximately 1,800 7.5-minute quads, more than 500 have been mapped and there are usually around ten that are in progress at any one time.

ON-007-01 — Aggregate Resources of Colorado —
ON-007-02 — Colorado Historic Coal Mines —
ON-007-03 — Mineral Resource Potential Derivative Map — Mineral resource derivative maps were constructed by the CGS using 7.5 minute quadrangles published under the current CGS STATEMAP geologic mapping program. Derivative maps are generalizations of detailed geological information that are used to assist non-geologists with evaluating complex geological information. These mineral derivative maps were created from digital geologic map data and historical mine locations to provide information on the general distribution of select potential mineral resource.

ON-007-06 — Critical Minerals of Colorado —
ON-007-07 — Reconnaissance of Potential Sand Sources in Colorado for Hydraulic Fracturing —

ON-010 — Colorado Groundwater Atlas — Includes the full extent of groundwater data currently available. This complex map is the GIS half of our new web-based Groundwater Atlas.

Colorado Abandoned Mine Land (AML) Information map — May also be accessed through the CDPHE at the Mine Impacted Streams TaskForce. The user interface is a GIS platform and includes AML information layers which can be projected on road maps, satellite imagery, property ownership maps, watershed maps, and so on.
The CGS began working on a select number of projects some time ago, to present them as StoryMaps, we’ve gotten one done:

Third-Party Resources:
ESRI, a major player in the GIS world introduced the online platform called StoryMaps in 2016. It has since become an important tool in conveying GIS information in a form that is more accessible to the general public.
The Bare Earth — This narrative features over 50 intriguing lidar images that help illustrate how geologists in Washington are using this fascinating technology to study the landscape.
